The people you meet at the start are the people accountable at the end.

Radhika B

Principal — Sustainability & ESG, Marketing, Sales & GTM

30+ YEARS

FMCG · Specialty Chemicals · Clean Technology · Industrial Decarbonisation

Radhika B has spent the last decade doing something most consultants cannot claim: convincing traditionally change-resistant industrial customers — in leather processing, paper manufacturing, and textile production — to replace the chemicals they have used for generations with green bio-based alternatives. This is not advisory work. It is commercial work of the hardest kind — building markets that did not exist, converting customers who did not want to change, and scaling a business from inception to industry leadership in sectors where the barriers to adoption are technical, cultural, and commercial simultaneously.

As a founding team member and BU Head at Proklean Technologies — India’s industry leader in green specialty chemicals for B2B industrial sectors — she built the entire commercial engine from zero: sales architecture, GTM, POC methodology, pricing, and global partnerships across India, the Middle East and Africa, Southeast Asia, and Europe. She scaled the business by over 1,500% in volume, achieved near-80% gross margins, and reached EBITDA positivity within 18 months — in a startup operating in markets that had never bought green chemistry before. Earlier, she led a commercial and organisational turnaround at Lotus Chocolates, taking a BIFR-listed company to sustained profitability — one of the less glamorous but most demanding forms of business leadership.

At Cerebratum, Radhika leads the Sustainability & ESG practice — where her decade of industrial decarbonisation experience is directly and practically applicable — and contributes to Marketing and Sales & GTM engagements where her track record of building commercial systems in resistant markets is the relevant credential. She is currently completing a PhD in Management, with research focused on strategy, scaling, and organisational effectiveness.

She has built markets that did not exist, in industries that did not want to change. That is the credential that matters in sustainability work.

P Kumar

Principal — Strategy, Operations, Product, Sales & GTM, People & HR

30+ YEARS

FMCG · Digital Media · Enterprise IT · SaaS

P Kumar is a business architect — someone who has built, run, and scaled complete enterprises rather than advised on parts of them. Across 33 years spanning FMCG, digital media, enterprise IT, and SaaS, the through-line has been the same: assuming full ownership of complex, multi-functional organisations and driving them to market leadership. The functions he has run include Finance, Product, Engineering, HR, Marketing, Customer Success, and Business Solutions — not sequentially, but simultaneously, as the accountable principal across all of them.

His career began in FMCG — brand management and consumer marketing at Bambino Agro Industries and Reynolds India, where he led the first in-India product design initiative at a company whose product direction had always been set from France. It moved through digital media at Sify Technologies, where he built the commercial model that made India’s first operationally cash-positive internet portal. Then enterprise IT at Polaris Software, where he unified a 10,000-person global organisation’s brand identity across geographies. And for nearly two decades at ExpertusONE — a globally recognised enterprise SaaS platform — where he built and scaled an organisation from first principles: financial architecture, product discipline, engineering transformation, people systems, and market positioning, all led directly.

At Cerebratum, P Kumar leads engagements across Strategy, Operations, Product Management, Sales & GTM, and People & HR — the practice areas where his operating experience is deepest and most directly applicable. He brings to every engagement what two decades of running a global enterprise produces: the ability to see the whole business, not just the function being worked on.

The functions he has run are not a portfolio of projects. They are a single, connected enterprise built over two decades.

The principal leads every engagement. The team behind the work is assembled for it.

Cerebratum does not maintain a large permanent team. What it maintains is a network of senior industry practitioners — writers, creatives, analysts, strategists, and specialists — who are assembled specifically for each engagement based on what that engagement requires. An FMCG brand that needs creative work gets a creative who has spent their career in FMCG agencies, not a generalist content writer. A technology platform that needs technical content gets a writer who has worked inside technology organisations. A green chemistry company that needs market research gets an analyst with industrial sector experience.

This model costs Cerebratum more than maintaining a standard team. It is also why the work is better — and why clients who engage Cerebratum for the first time almost always stay. The practitioner assembled for your engagement has done this specific kind of work before, in your specific kind of industry. They are not learning on your brief.

One thing does not change regardless of who is assembled: the principal is the only person who speaks to the client. The only person in meetings. The only person on emails. The team behind the work executes with full competence — but the client’s relationship, and the accountability for what is delivered, sits with the principal alone. You pay for the principal. You get the principal. The team that makes it possible is our investment, not yours.

how the assembly works in practice

The assembly is invisible to the client. The principal is the single point of contact, accountability, and communication — always.

The first conversation is with a principal. Not a coordinator, not a salesperson.

Tell us what you’re working on. We’ll tell you which principal is the right fit — and what the engagement would look like.
